[Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure are listed and described.

The movable support structure of the present disclosure is as follows.

(1) A first component having a movable support portion and a retaining restricting portion, and a second component having a supported portion and a receiving portion, wherein the movable support portion is movable along the first direction. The supported portion that has slid toward the supporting portion is restricted from moving backward in the slide movement direction, and the supported portion that has slid is moved in the first direction and in a second direction orthogonal to the first direction. and the retaining restricting portion moves from a position away from the receiving portion on the side opposite to the second component toward the side on which the supported portion slides. It extends in a posture gradually approaching the receiving portion, and in a state in which the supported portion is slid toward the movable support portion, the retaining surface formed at the tip of the retaining restricting portion reaches the receiving portion. On the other hand, it is a movable support structure that can be contacted from a direction in which the supported portion is to escape. When the supported part tries to come out from the movable support part, it is conceivable that a force in the direction of removal of the supported part and a force toward the first component are applied to the tip of the restraining part. However, such force is effectively received by the slanted retainer restricting portion. Therefore, the retaining restricting portion itself is difficult to deform so as to displace the tip portion toward the first component. As a result, release of the catching between the retaining restricting portion and the receiving portion is suppressed. This makes it difficult for the second part to separate from the first part when the second part is movably supported relative to the first part.

(2) The pressing surface formed at the tip of the retaining restricting portion contacts the receiving portion from the side opposite to the second component, and presses the second component away from the first component. good too. The second part is less likely to rattle with respect to the first part.

(3) a side projecting portion is formed on at least one side of a tip end of the retaining restricting portion, and the side projecting portion contacts the second component from a side opposite to the second component; The second part may be pressed away from the first part.

(4) One of the movable support portion and the supported portion has a pair of insertion protrusions, and the other of the movable support portion and the supported portion has a pair of insertion protrusions into which the pair of insertion protrusions are inserted. A guide groove is provided, and a gap is provided at an end of the pair of guide grooves on the side of the insertion opening into which the pair of insertion protrusions is inserted so that the pair of insertion protrusions can be inserted into the pair of guide grooves. A retaining protrusion may be formed to partially block the pair of guide grooves in the state of being held. It becomes difficult for the pair of insertion protrusions to come off from the pair of guide grooves, and it becomes difficult for the second component to separate from the first component.

(5) the movable support portion has a back side receiving portion that faces the supported portion slidingly moved toward the movable support portion along the first direction on the back side in the slide movement direction; The back side receiving portion may have a pair of split back side receiving portions that are separated in the second direction with a gap therebetween. The supported portion can be stably received by the pair of divided back side receiving portions while achieving weight reduction.

[Details of the embodiment of the present disclosure]
Specific examples of the movable support structure of the present disclosure are described below with reference to the drawings. The present disclosure is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all modifications within the meaning and scope of equivalents of the scope of the claims.

[Embodiment]
A movable support structure according to an embodiment will be described below. In this embodiment, an example will be described in which the movable support structure is a cover attached to an opening of a device housing. FIG. 1 is an exploded perspective view showing the cover 20. FIG. FIG. 2 is a front view showing a state in which the cover 20 is attached to the opening 11 of the device housing 10. FIG.

The device housing 10 is a member made of metal or the like, and is, for example, a case of an electrical device. An opening 10 h is formed in the device housing 10 . The opening 11 is attached to this opening 10h. The opening 11 includes a tubular portion 12 and a bracket portion 13 . The cylindrical portion 12 is made of resin or the like. Here, the tubular portion 12 is formed in an elongated tubular shape. The bracket portion 13 is formed of a metal plate or the like. The bracket portion 13 protrudes to the outer peripheral side of the tubular portion 12 at an axially intermediate portion of the outer peripheral portion of the tubular portion 12 . The main bracket portion 13 is fixed to the device housing 10 with screws or the like. With the bracket portion 13 fixed to the device housing 10, the cylindrical portion 12 is positioned within the opening 10h of the device housing 10 in plan view. For example, the tubular portion 12 and the bracket portion 13 are integrated by molding the tubular portion 12 with a portion of the bracket portion 13 as an insert portion.

The space inside the cylindrical portion 12 is open to the inside and outside of the device housing 10 . The cover 20 is a cover that closes the outer opening of the tubular portion 12 .

The cover 20 has a cover body 30 and a connector 50 .

The cover main body 30 is a member made of resin or the like, and formed into a shape that can be fitted into the cylindrical portion 12 . Here, the cover main body 30 is formed in a plate shape having a shape corresponding to the shape of the inner peripheral surface of the cylindrical portion 12 in plan view. Here, since the cylindrical portion 12 is formed in an elongated cylindrical shape, the cover main body 30 is formed in an oval disk shape. The opening of the tubular portion 12 is closed by fitting the cover main body 30 into the tubular portion 12 .

Here, a shield cover 28 made of a metal plate or the like is attached to the outside of the cover body 30 . Here, the shield cover 28 is fixed to the cover body 30 using screws 29 or the like. A shield cover 28 covers the periphery of the opening 11 to perform electromagnetic shielding while the cover main body 30 is fitted into the tubular portion 12 . In this state, the shield cover 28 is screwed to the bracket portion 13 and grounded to the device housing 10 . The shield cover 28 is not essential and may be omitted.

The connector 50 is a member held so as to be relatively movable within a predetermined range with respect to the cover body 30 . Here, the connector 50 is movably held in a portion facing the inside of the device housing 10 with respect to the cover body 30 . A mating connector 16 is provided in the device housing 10 (see FIG. 2). The mating connector 16 is a connector connectable to the connector 50 . The mating connector 16 is supported at a position where it can be connected to the connector 50 held by the cover body 30 in a state where the cover body 30 is fitted into the cylindrical portion 12 .

For example, it is assumed that the mating connector 16 is a connector having two terminals and the connector 50 is also a connector having two terminals. Also, it is assumed that the two terminals of the connector 50 are in a conductive state by a short-circuiting member such as an electric wire. When the cover 20 is attached to the opening 11, the connector 50 is connected to the connector 16 on the other side. Then, the two terminals of the mating connector 16 are connected to the corresponding two terminals of the connector 50 to be in a conducting state.

A manufacturing error, an assembly error, or the like may occur in the arrangement position of the mating connector 16 with respect to the opening 11 . Also, manufacturing errors, assembly errors, and the like may occur in the holding position of the connector 50 with respect to the cover body 30 . In order to absorb such errors, the connector 50 is movably supported within a predetermined range with respect to the cover body 30 .

In the present embodiment, the cover main body 30 is an example of a first component that has a movable support portion and a retaining regulating portion. The connector 50 is an example of a second component having a supported portion and a receiving portion. A movable support portion 40 is provided at a position near one end in the width direction of the cover body 30 . Here, the cover main body 30 is formed in an elongated shape in plan view, and the longitudinal direction is sometimes called the width direction, and the short direction is sometimes called the depth direction. The movable support portion 40 movably supports the connector 50 . The position of the movable support part 40 is not particularly limited. A supported portion 60 is provided at the base end portion of the connector 50 . The connector 50 is movably supported by the movable support portion 40 via the supported portion 60 .

The movable support portion 40 and the supported portion 60 will be described more specifically. 3 and 4 are perspective views showing the movable support portion 40 and the supported portion 60. FIG. In FIGS. 3 and 4, the supported portion 60 before being supported by the movable support portion 40 is shown in phantom lines. FIG. 5 is a front view of the movable support portion 40. FIG. FIG. 6 is a partial cross-sectional view taken along line VI--VI of FIG.

The movable support portion 40 supports the supported portion 60 slidably moved in the first direction X toward the movable support portion 40 so as to be movable in the first direction X and the second direction Y. As shown in FIG. Here, the first direction X is the direction in which the supported portion 60 moves toward the movable support portion 40 when the supported portion 60 is supported by the movable support portion 40 . The second direction Y is a direction orthogonal to the first direction X. As shown in FIG. Here, the second direction Y is orthogonal to both the first direction X and the third direction Z when the extension direction of the connector 50 with respect to the cover body 30 is the third direction Z. As shown in FIG. Note that the third direction Z may be grasped as the connection direction of the connector 50 with respect to the connector 16 . In addition, the movable support portion 40 supports the supported portion 60 in the first direction X while restricting the movement of the supported portion 60 to the rear side in the slide movement direction.

More specifically, the movable support portion 40 includes a pair of slide support portions 42 and a back side receiving portion 46 .

A pair of slide support portions 42 are formed so as to protrude from a portion of the cover body 30 facing the device housing 10 with a gap therebetween. The slide support portion 42 includes a plate-like portion that spreads in the XZ plane. The pair of slide support portions 42 are opposed to each other with a gap in the Y direction, and the supported portion 60 is arranged between them. A pair of guide grooves 43 are formed in the inward portions of the pair of slide support portions 42 (here, the inward portions at the distal end portions of the slide support portions 42). The guide groove 43 is formed along the sliding movement direction of the supported portion 60, which is the X direction here. The pair of guide grooves 43 are open on the sides facing each other and on the one end side in the extending direction. The end portion of the pair of guide grooves 43 on the one end side in the extending direction is an insertion opening side end portion into which a pair of insertion protrusions 62 to be described later are inserted.

A retaining protrusion 44 is formed at the end of the pair of guide grooves 43 on the insertion port side. The retaining protrusion 44 partially closes the guide groove 43 at the insertion opening side end of the guide groove 43 . At the end of the guide groove 43 on the side of the insertion port, a gap is provided between the retaining protrusion 44 and the inner surface of the guide groove 43 so that the insertion protrusion 62 can be inserted therein. Here, the retaining protrusion 44 is formed to protrude from the surface of the guide groove 43 on the cover body 30 side. Between the retainer protrusion 44 and the surface of the guide groove 43 on the connector 50 side, a gap is formed which is about the same (preferably the same) as the thickness dimension of the insertion protrusion 62 . In addition, the retaining protrusion 44 includes a guide surface 44f1 that gradually protrudes toward the rear side of the supported portion 60 in the slide movement direction. When the insertion protrusion 62 is inserted into the guide groove 43, the insertion protrusion 62 contacts the guide surface 44f1 and is guided into the gap. Thereby, the insertion protrusion 62 is smoothly guided into the guide groove 43 . A surface of the retaining projection 44 on the intermediate side in the extending direction of the guide groove 43 is formed as a retaining surface 44f2 orthogonal to the first direction X. As shown in FIG. When the insertion protrusion 62 is housed in the guide groove 43 beyond the retaining protrusion 44, the insertion protrusion 62 contacts the stop surface 44f2 and becomes difficult to escape from the guide groove 43.

The back side receiving portion 46 is provided on the back side of the supported portion 60 in the slide movement direction of the slide support portion 42 . The back side receiving portion 46 is provided at a position facing the supported portion 60 that slides toward the movable support portion 40 on the back side in the slide movement direction.

Here, the back side receiving portion 46 includes a pair of split back side receiving portions 46a, 46a. The pair of split back side receiving portions 46 a , 46 a are provided on each of the pair of slide support portions 42 . A part of the divided back side receiving portion 46 a closes the other end side of the guide groove 43 in the extending direction. The other portion of the rear side receiving portion 46 a projects from the distal end portion of the slide support portion 42 on the rear side in the slide direction toward between the pair of slide support portions 42 . The pair of divided back side receiving portions 46a, 46a are separated in the second direction Y with a gap therebetween. The pair of split back side receiving portions 46a, 46a may be connected to each other.

The supported portion 60 is a portion forming the base end portion of the connector 50 . Here, the base end portion 51 of the connector 50 is formed in a shape that protrudes in the first direction X with respect to the tip side portion of the connector 50 . Since the proximal end portion 51 of the connector 50 protrudes from the distal end portion, an insertion protrusion 62, which will be described below, can be formed longer. As a result, the insertion protrusion 62 is easily stabilized within the guide groove 43 .

The supported portion 60 includes a pair of insertion projections 62 projecting from both sides of the base end portion 51 of the connector 50 . The pair of insertion protrusions 62 is formed in an elongated plate shape that can be fitted into the guide groove 43 . The space between the outward surfaces of the pair of insertion projections 62 is larger than the space between the inner surfaces of the pair of slide support portions 42, but smaller than the space between the bottom surfaces of the pair of guide grooves 43. As shown in FIG. Also, the dimension between both side surfaces of the base end portion 51 of the connector 50 is smaller than the distance between the inner surfaces of the pair of slide support portions 42 . Therefore, the supported portion 60 of the base end portion 51 of the connector 50 can move within a predetermined range along the second direction Y, which is the direction connecting the pair of slide support portions 42 .

The length dimension of the insertion protrusion 62 is smaller than the length dimension of the guide groove 43 . Therefore, in the extending direction of the guide groove 43 , the insertion protrusion 62 can be in a state of being accommodated within the guide groove 43 . In addition, the width of the guide groove 43 is larger than the thickness of the insertion projection 62 here. Therefore, the insertion protrusion 62 can move in the guide groove 43 in the third direction Z. As shown in FIG. Therefore, the supported portion 60 is movably supported within a predetermined range in the third direction Z as well. As a result, the connector 50 can be tilted within a predetermined range with respect to the cover body 30 , and the connector 50 can be tilted according to the posture of the mating connector 16 . Therefore, the work of connecting the connector 50 to the mating connector 16 can be performed smoothly.

Further, the movement of the supported portion 60 is restricted by the inner side receiving portion 46 in the direction of sliding movement in the first direction X. As shown in FIG. In the direction opposite to the sliding direction, that is, in the direction in which the supported portion 60 is pulled out of the movable support portion 40, the supported portion 60 is pulled off by the engagement between the receiving portion 64 and the stopper portion 48, which will be described below. movement is restricted.

The configuration in which the movable supporting portion supports the supported portion movably within a predetermined range is not limited to the above example. For example, the movable support portion is a protrusion having a T-shaped cross section, and the supported portion is a groove having a T-shaped cross section into which the protrusion having a T-shaped cross section is slidably fitted with play. good too.

Further, in the above example, the movable support portion 40 has a pair of guide grooves 43 and the supported portion 60 has a pair of insertion protrusions 62 . Contrary to this configuration, the movable support portion may have a pair of insertion projections, and the supported portion may have a pair of guide grooves.

The supported portion 60 is retained from the movable support portion 40 by contacting the retaining portion 48 with the receiving portion 64 .

A base end portion 51 of the connector 50 is open when viewed from the movable support portion 40 side. A receiving portion 64 is formed on the base end portion 51 . Here, of the peripheral wall portion surrounding the opening formed in the proximal end portion 51 , the distal end portion of the wall portion on the far side in the slide movement direction is the receiving portion 64 . The receiving portion 64 is formed in a plate shape orthogonal to the extending direction of the pair of insertion protrusions 62 . Of the edge portion of the receiving portion 64, a portion on the back side in the slide movement direction (outward portion) is formed in a chamfered slope shape. Here, of the edge portion of the receiving portion 64, the portion on the front side in the slide movement direction (inward portion) is also formed in a chamfered slope shape. Both surfaces of the portion of the receiving portion 64 on the back side of the portion formed in the slope shape are formed on surfaces orthogonal to the slide movement direction.

The retaining restricting portion 48 is provided on the movable support portion 40 . The retainer restricting portion 48 extends from a position away from the receiving portion 64 on the opposite side of the connector 50 toward the side where the supported portion 60 slides in a posture of gradually approaching the receiving portion 64 . there is More specifically, the base extends from the intermediate portion in the first direction X toward the side into which the supported portion 60 is inserted, which is the back portion between the pair of slide support portions 42 of the movable support portion 40 . A strip 47 extends. A retaining restricting portion 48 is provided so as to fold back at the tip portion of the extending base piece 47 . Between the pair of slide support portions 42 , the retaining restricting portion 48 is arranged so as to move in the sliding movement direction of the supported portion 60 with respect to the movable support portion 40 as it goes from the back side to the tip side of the pair of slide support portions 42 . It extends in an inclined position. Here, the portion of the retainer restricting portion 48 excluding the folded portion and the tip portion is in the shape of a straight plate. The distal end portion of the retaining restricting portion 48 is positioned deep in the slide movement direction of the supported portion 60 between the pair of guide grooves 43 . With the supported portion 60 slidably inserted into the movable support portion 40 , the distal end portion of the retainer restricting portion 48 is arranged at a position where it can come into contact with the receiving portion 64 . The retaining restricting portion 48 can be elastically deformed around its base side. As a result, the retainer restricting portion 48 can be displaced along the third direction Z, which is the longitudinal direction of the connector 50 . Since the retaining restricting portion 48 extends obliquely, the retaining restricting portion 48 is relatively long. As a result, it is possible to provide a sufficient elastic deformation region in the stopper restricting portion 48 in a more space-saving manner.

The tip of the retaining restricting portion 48 includes a retaining surface 48f1. Here, the distal end portion of the retaining restricting portion 48 includes a portion 48a that protrudes toward the connector 50 in the third direction Z. As shown in FIG. A surface of the portion 48a on the rear side in the slide movement direction of the supported portion 60 is a retaining surface 48f1. In a state in which the supported portion 60 slides toward the movable support portion 40, the retaining surface 48f1 moves in the direction in which the supported portion 60 is prevented from falling out from the receiving portion 64 (that is, the sliding movement direction of the supported portion 60). front side).

More specifically, in a natural state in which the retaining regulating portion 48 is not elastically deformed, the portion 48a including the retaining surface 48f1 and the receiving portion 64 are seen through the supported portion 60 along the sliding movement direction. exist in overlapping positions. In particular, the insertion protrusion 62 is in contact with the inner surface of the connector 50 in the guide groove 43 (that is, the supported portion 60 is at the farthest position from the cover main body 30 within the movable range of the movable support portion 40). However, this positional relationship is established. Therefore, when the supported portion 60 is slid and attached to the movable support portion 40, the retaining surface 48f1 of the retaining restricting portion 48 comes into contact with the receiving portion 64 to prevent the supported portion 60 from being detached. be. This state is the retaining state.

In addition, the retaining restricting portion 48 is moved from the posture in the retaining state described above to a direction in which the supported portion 60 is inserted into the movable support portion 40 in a relative passage path of the receiving portion 64, that is, the cover main body. It can be elastically deformed to the 30 side. When the supported portion 60 of the connector 50 is attached to the movable support portion 40 of the cover body 30, the receiving portion 64 contacts the inclined surface of the portion 48a from the opposite side of the retainer surface 48f1. As a result, the retainer regulating portion 48 can be deformed in the retracting direction. Then, when the portion 48a passes over the receiving portion 64, the retaining restricting portion 48 returns to its original shape and enters the retaining state described above.

There is a difference between the position where the supported portion 60 is prevented from coming off by the retaining surface 48f1 and the position where the back side receiving portion 46 restricts the movement to the back side. Here, the distance between the retainer surface 48f1 and the far side receiving portion 46 is larger than the thickness of the receiving portion 64. As shown in FIG. Accordingly, the supported portion 60 can move in the first direction X within a predetermined range.

A tip portion of the retainer restricting portion 48 includes a pressing surface 48f2. Here, the distal end portion of the retainer restricting portion 48 includes a portion 48b that projects in the first direction X toward the rear side of the supported portion 60 in the slide movement direction. A surface of the portion 48b that faces the connector 50 in the third direction Z is a pressing surface 48f2. The pressing surface 48f2 is provided at a position where it can come into contact with the receiving portion 64 from the cover main body 30 side when the insertion protrusion 62 is accommodated in the guide groove 43 . For example, the insertion protrusion 62 is in contact with the inner surface of the connector 50 in the guide groove 43 (that is, the supported portion 60 is at the farthest position from the cover main body 30 within the movable range of the movable support portion 40). , and is provided at a position where it can come into contact with the receiving portion 64 from the cover main body 30 side. FIG. 6 illustrates how the portion 48b including the pressing surface 48f2 is arranged in a region overlapping the receiving portion 64 in the initial state in which the retainer restricting portion 48 is not elastically deformed. When the supported portion 60 is slid into the movable support portion 40, the pressing surface 48f2 formed at the tip of the retaining restricting portion 48 comes into contact with the receiving portion 64 from the side opposite to the connector 50. The connector 50 is pressed away from the cover body 30. - 特許庁

Further, a side protruding portion 49 is formed on at least one side portion of the distal end of the retaining restricting portion 48 . Here, a pair of lateral projecting portions 49 are formed on both sides of the distal end of the retaining restricting portion 48 . More specifically, a side protruding portion 49 is provided closer to the cover body 30 than the portion 48 a of the distal end portion of the retaining restricting portion 48 . In the first direction X, the positions of the pressing surface 48f2 and the side protruding portion 49 are out of alignment. A surface of the lateral projecting portion 49 on the connector 50 side is provided at the same position in the third direction Z as the pressing surface 48f2. With the pressing surface 48f2 in contact with the receiving portion 64, the side projecting portion 49 contacts the supported portion 60 from the cover body 30 side. Here, the pair of side protruding portions 49 are in contact with both side wall portions of the peripheral wall portion surrounding the opening in the base end portion 51 of the connector 50 . As a result, the pair of side protruding portions 49 also come into contact with the connector 50 from the side opposite to the cover body 30 and press the connector 50 away from the cover body 30 .

According to the movable support structure configured in this manner, the retaining restricting portion 48 receives from a position away from the receiving portion 64 on the side opposite to the connector 50 toward the side where the supported portion 60 slides. It extends in a posture gradually approaching the portion 64 . A retaining surface 48f1 at the tip of the retaining restricting portion 48 comes into contact with the receiving portion 64 to prevent the supported portion 60 from coming off. When the supported portion 60 attempts to come out of the movable support portion 40, it is conceivable that a force in the direction in which the supported portion 60 comes off and a force in the direction of the cover main body 30 are applied to the distal end portion of the retaining restricting portion 48. . However, such a force is effectively received by the rigidity in the extending direction of the retaining restricting portion 48 in the oblique posture. For this reason, the retaining restricting portion 48 itself is difficult to deform such that the distal end thereof is displaced toward the cover main body 30 side. As a result, the release of the engagement between the retaining restricting portion 48 and the receiving portion 64 is suppressed. This makes it difficult for the connector 50 to separate from the cover main body 30 when the connector 50 is relatively movably supported with respect to the cover main body 30 .

A pressing surface 48 f 2 formed at the tip of the retainer restricting portion 48 contacts the receiving portion 64 from the side opposite to the connector 50 and presses the connector 50 away from the cover body 30 . Therefore, the connector 50 is less likely to rattle with respect to the cover body 30 . Thereby, for example, vibration of the connector 50 is suppressed. Also, other measures for suppressing vibration of the connector 50 are not required. It is also effective as a configuration for suppressing vibration of the connector 50 when the movable width of the supported portion 60 with respect to the movable support portion 40 is set large.

In addition, since the connector 50 is pressed away from the cover main body 30 by the lateral projecting portion 49, the connector 50 is less likely to rattle with respect to the cover main body 30. FIG. The lateral protrusion 49 may be omitted. In particular, a pair of lateral protrusions 49 are provided on both sides of the pressing surface 48f2, so that the distal end portion of the restraining portion 48 can press the connector 50 stably.

Further, since the guide groove 43 is provided with the retaining protrusion 44 , the insertion protrusion 62 is difficult to be pulled out of the guide groove 43 , and the connector 50 is difficult to separate from the cover main body 30 .

Further, the distal end portion of the retainer restricting portion 48 pushes the receiving portion 64 toward the connector 50 on the back side of the supported portion 60 in the slide movement direction. For this reason, the connector 50 tends to tilt toward the front in the slide movement direction of the supported portion 60. In other words, the end of the insertion projection 62 on the side of the retaining projection 44 is displaced toward the cover main body 30. , may be tilted easily. In this embodiment, the retaining protrusion 44 is provided in the guide groove 43 on the side of the cover main body 30 . Therefore, even if the connector 50 is tilted as described above, the insertion protrusion 62 is likely to come into contact with the retaining protrusion 44, effectively preventing the supported section 60 from detaching from the movable support section 40. FIG.

In addition, since the pair of split back side receiving portions 46a, 46a are separated through the gap, the pair of split back side receiving portions 46a, 46a stably receive the supported portion 60 while achieving weight reduction. can be done. Also, it is possible to reduce the amount of resin used.

[Variation]
In the above embodiment, the example in which the cover main body 30 is the first component and the connector 50 is the second component has been described.
